| 摘要 |
A stage assembly (224) for moving and positioning a device (300) includes a device table (308), a device holder (312) that retains the device (300), and a stage mover assembly (204). In some embodiments, the stage assembly (224) allows precise rotation of the device (300) between a first position and a second position. Additionally, the stage assembly (224) can include a lock assembly (342) that selectively locks the device holder (312) to the device table (308) without influencing the flatness of the device (300) and without deflecting and distorting the device holder (312) and the device (300).
